Contact Lenses
In this section, you can find some information and frequently asked questions about contact lenses. However, we always recommend relying on a specialist for the selection and purchase of contact lenses. This is because using products that are not suitable for your eyes or of poor quality can be very dangerous.
Soft Contact Lenses
Are all contact lenses the same?
Not all contact lenses are the same. They can be made from hundreds of different biocompatible materials. Additionally, contact lenses differ from one another in terms of geometry. Soft contact lenses also vary in their duration; they can be daily disposable, weekly, bi-weekly, monthly, quarterly, etc.
Which type of contact lens is best for me?
Each of us has different characteristics and needs, so a pre-application assessment is always necessary. By analyzing the quantity and quality of the tear film and the ocular surface through corneal topography, it is possible to determine which lens is most suitable.
If I wear a daily contact lens for just a few hours, can I reuse it?
Absolutely not. Daily contact lenses are single-use lenses, and once they are worn, they cannot be reused.
Is it true that it is dangerous for contact lenses to come into contact with tap water?
Yes, it is true. Tap water can contain a protozoan called Acanthamoeba, which can use the contact lens as a carrier and cause serious keratitis. It is always advisable to wear contact lenses with clean and dry hands, and to avoid direct contact with water, such as swimming in the sea, pools, or using saunas while wearing lenses. Of course, cleaning the lens case is also essential and should not be done with tap water but with the appropriate solutions.
When should I choose a daily contact lens and when a monthly one?
There are various factors that can guide the choice between a daily or monthly contact lens, such as a person's needs, corneal parameters, refraction, and tear production.
Contact Lenses for Keratoconus
What is keratoconus?
Keratoconus is a bilateral corneal condition (usually, the cone in one eye is more advanced than in the other), progressive, and non-inflammatory, which causes thinning of the cornea and its bulging. It typically leads to refractive errors that are not easily correctable with glasses, making the use of contact lenses necessary.
When does it develop?
It usually develops at a young age and tends to stabilize around the age of 30.
How does keratoconus affect my vision?
When affected by keratoconus, the cornea is no longer a regular surface, usually resulting in myopia and astigmatism. For this reason, keratoconus may not be recognized in its early stages. A prompt diagnosis by an ophthalmologist is crucial.
What type of contact lenses are used?
The new contact lenses for keratoconus are made from materials that allow maximum oxygen permeability and provide the highest protection for the cone apex. Contact lenses for keratoconus can be soft, hybrid, or rigid. The choice of lens type is made after a thorough analysis, as it is necessary to evaluate several factors, such as the stage of the cone, its position, tear production, and eyelid interaction.
Is it true that if contact lenses are not applied carefully, they can worsen the severity of the cone?
A cornea affected by keratoconus is thin and dystrophic, making it delicate. It is essential to respect the corneal surface, particularly the cone apex. An application that does not respect the corneal surface can further compromise it; the lens, by interacting with the cone apex, can worsen its severity. Besides proper application, follow-up is crucial to ensure there are no corneal alterations while wearing the lens that could compromise its functionality and ocular health. In cases of corneal conditions, it is essential to rely on specialized centers for contact lens fitting to ensure all possible solutions are considered.
Orthokeratology Contact Lenses
What is it?
Orthokeratology is a non-surgical, non-invasive, controlled, and reversible technique that allows for the correction of refractive errors through the use of reverse geometry RGP contact lenses worn overnight. Although it might seem like an innovative technique, it has been around since 1962.
Who can do it?
Orthokeratology is a treatment with no age limits. However, very high myopia or astigmatism and hypermetropia above three diopters may present limitations. In any case, as with all other types of contact lenses, a pre-application assessment is necessary to ensure there are no contraindications to wearing contact lenses.
How long does it take to achieve the corrective effect?
The correction time for visual defects is subjective. The time needed to achieve full compensation can vary based on the severity of the visual defect; the higher it is, the more time it will require. However, noticeable results can often be seen after just one night of wearing the contact lenses.
Is it dangerous?
Various international studies have shown that the risk of complications is comparable to that of using conventional contact lenses. It is safe to use as long as you always follow the instructions of the contact lens specialist. It can become dangerous if maintenance is neglected or the instructions are not followed properly.
Is it effective in controlling myopic progression?
It is well known that an increase in myopia is associated with a higher risk of ocular conditions such as retinal detachment, myopic maculopathy, cataracts, and glaucoma. For this reason, controlling myopic progression is crucial for both parents and specialists. Numerous scientific studies have been conducted on controlling myopic progression, and it has been shown that using methods to counteract it can reduce its progression by over 50%. This means halving the worsening that would occur when using the wrong correction method. Therefore, controlling myopic progression involves using scientifically validated methods to slow the increase in myopia, and one of these methods is Orthokeratology.
What are the advantages?
One advantage is that it can be a substitute for glasses and serves as a valid alternative to getting rid of the daytime use of conventional contact lenses, making it very convenient for those who play sports or work in very dusty environments. It is completely reversible; when the lenses are discontinued, the cornea returns to its original condition. It is effective in controlling myopic progression and is used in school-age children to control the increase in visual defects, thus slowing down the worsening.
What are the disadvantages?
The disadvantages of this type of lens are similar to those of conventional contact lenses for prolonged use. It requires very careful hygiene and always following the instructions of the contact lens specialist. While its reversibility is an advantage, it can also be a disadvantage since you must be consistent with nightly use to ensure effective treatment. Regular check-ups with your contact lens specialist optometrist and ophthalmologist are required.
Post-Surgery Contact Lenses
When are they necessary?
There are various situations where the use of contact lenses with a design suitable for a cornea with a modified profile is necessary, such as after refractive surgery or post-transplant.
After undergoing refractive surgery, it may happen that the desired result is not achieved. With the corneal profile altered, a soft contact lens or glasses may no longer be sufficient. In these cases, RGP lenses with a specific geometry are used to properly align with the corneal profile and provide the best visual result. The same principle applies in post-transplant cases; since the cornea has a modified profile, it requires the use of special RGP contact lenses.
